1. When finger stop for my son (4), so that no fingers come into the picture.
Works just fine, but fails in practice because the trigger is quite small and feels barely recognizable and the intermediate for AF activation has no distinct pressure point. The zoom button in turn is not only tiny, but also stiff, but that usually works. Conclusion: outdoor cameras with the lens on the top left on the corner there are much better than children Kamers if one pays attention to unique tactile controls.
2. to protect against scratching by the beliegenden lens cap and the filter holder (40.5 mm)
Scratch protection: perfectly solved. Just a wrist strap that connects the lid firmly with the ring would still be great!
Filter holder: with the limitations that I describe in point 3.
3. As converter holder, that his real purpose lt. Olympus
The adapter has a standard filter thread, but unfortunately from a superficially rough plastic, which means that the converter must be recognized unwieldy and fiddly because the thread simply not clean hold each other, and usually only after many attempts (and I really exercise and not ten left thumb). If they have then first taken, you have to be very careful, the filter or converter not overtighten turn up because then inevitably going with the releasing of the adapter. In the long run, the camera-side bayonet leiert assume also. All this would not be a problem at a reasonable adapter burnished brass. I do not understand why Olympus had to save because in the final meters to the quality, especially in the sporty price!
Conclusion: it would have the time already, I would have tried first by far the cheaper replica. So I'm going to have this complaint expected and I hope that it will eventually be a metal.
